For enhanced safety, the front and rear seat shoulder belts of the Mercedes C-Class Sedan have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Volkswagen Jetta GLI doesn’t offer pretensioners for its rear seat belts.
The C-Class Sedan’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Jetta GLI doesn’t offer pre-crash pretensioners.
In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the C-Class Sedan are reminded to check the back seat if they opened the rear door before starting out. The Jetta GLI doesn’t offer a back seat reminder.
The Mercedes C-Class Sedan has a standard driver’s side knee airbag mounted low on the dashboard. The knee airbag helps prevent the driver from sliding under the seatbelts or the main frontal airbag; this keeps the driver better positioned during a collision for maximum protection. A knee airbag also helps keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Jetta GLI doesn’t offer knee airbags.
The C-Class Sedan has a standard front seat center airbag, which deploys between the driver and front passenger, protecting them from injuries caused by striking each other in serious side impacts. The Jetta GLI doesn’t offer front seat center airbags.
With its available Active Brake Assist with Cross-Traffic Function, the Mercedes C-Class Sedan is better at preventing collisions with pedestrians than the Volkswagen Jetta GLI, according to the Insurance Institute for Highway Safety:

The C-Class Sedan offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Jetta GLI doesn’t offer all-wheel drive.
Earlier warning of stopped traffic, traffic signals, dangerous road conditions, weather, or accidents, can keep driver's safer and prevent crashes. The C-Class Sedan offers optional Car-to-X Communication, a system that seamlessly communicates important warnings to the driver about impending danger, if they're available. The Jetta GLI doesn’t offer a system that can receive automated systems from infrastructure or other vehicles.
The C-Class Sedan offers an optional Surround View System to allow the driver to see objects all around the vehicle on a screen. The Jetta GLI only offers a rear monitor.
The C-Class Sedan’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The Jetta GLI doesn’t offer a driver alert monitor.
Both the C-Class Sedan and the Jetta GLI have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, post-collision automatic braking systems, daytime running lights, blind spot warning systems, rearview cameras, rear cross-path warning and available lane departure warning systems.
The Mercedes C-Class Sedan weighs 514 to 716 pounds more than the Volkswagen Jetta GLI. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.
Side impacts caused 23% of all road fatalities in 2018, down from 29% in 2003, when the Insurance Institute for Highway Safety introduced its side barrier test. In order to continue improving vehicle safety, the IIHS has started using a more severe side impact test: 37 MPH (up from 31 MPH), with a 4180-pound barrier (up from 3300 pounds). The results of this newly developed test demonstrates that the Mercedes C-Class Sedan is safer than the Jetta GLI:

The Mercedes C-Class Sedan achieved a “Top Safety Pick” rating from the Insurance Institute for Highway Safety (IIHS) for the 2024 model year. This recognition was based on its impressive performance in the small overlap frontal crash test, updated side impact crash test, headlight evaluations, and pedestrian crash prevention testing. The Jetta GLI is not a “Top Safety Pick” for 2024.
